Willam Thomas Pecora was born on February 1, 1913, in Belleville, New Jersey, son of Cono and Anna (Amabile) Pecora. Both parents were born in southern Italy, in the village of Sant'Arsenio. Pecora was the ninth of 10 children, four boys and six girls. His family was in the wholesale import business. In 1929, Pecora was awarded the Charles H. K. Halsey Scholarship that provided a $1,000 annual scholarship at Princeton University, where he majored in geology and geologic engineering; he was awarded a bachelor's degree in 1933. After graduation, he stayed on at Princeton as a geology tutor.[1]

Pecora was the United States intercollegiate fencing champion in 1933 and went to Germany at the 1936 Summer Olympics in Berlin as a member of the United States Olympic fencing team.[1][2][3] He married Ethelwyn Elizabeth Carter from Franklin County, Kentucky on April 7, 1947. They had two children, William Carter Pecora born in 1949 and Ann Stewart Pecora born in 1953.

In 1949, he started a large-scale geologic mapping program of eight fifteen-minute quadrangles in the Bearpaw Mountains. The first four of these maps was published in 1957 as Miscellaneous Geologic Investigation Maps and the other four were published in bulletins starting in 1960 and ending in 1963. In 1956, Pecora published a review paper on carbonatites which are carbonate-silicate rocks containing a variety of minerals, including impressive reserve of rare commodities such as titanium, zirconium, and uranium. In a 1962 paper, Pecora concentrated on the carbonatite deposits in the Bearpaw Mountains.

In 1957, Pecora was selected as Chief of the Branch of Geochemistry and Petrology within the United States Geological Survey. He established programs in geochronology, experimental petrology, and mineralogy. In 1961, he returned to research. He was named Chief Geologist in 1964 and a year later was appointed Director of the United States Geological Survey by President Lyndon B. Johnson. As Director, he pressed for programs that would be responsive to emerging national problems, such as investigations of gold resources and off-shore oil and gas exploration. He established the National Center of Earthquake Research in response to problems revealed by the 1964 Alaska earthquake. As Director, he advocated for the creation of a remote sensing satellite that would be used to gather information about the surface of the Earth, which became the Landsat program, the longest-running project for gathering images of Earth from space.[4]

Pecora also addressed the discovery of large oil reserves of oil and gas on the north coast of Alaska in 1968. Under his Direction, the U.S. Geological Survey made a careful study of the geologic aspects of the proposed pipeline route. From 1947 to 1967 he was a member of the United States Civil Service Commission's Board of Examiners for Geology, concerned with the development and maintenance of standards in the selection of geologists for federal employment. He was an active member of the Survey's Pick and Hammer shows, which were presented annually to make fun of top Survey managers. In 1970, Pecora expressed his opposition to burying the Trans-Alaska Pipeline System, as it would be unsafe to place an underground pipeline in Arctic land He was appointed to serve as Undersecretary of the United States Department of Interior by President Richard Nixon on April 1, 1971.[2]

He died at age 59 on July 19, 1972 at George Washington University Hospital after having surgery for diverticulitis the previous month. A statement from President Nixon called him "a remarkable civil servant and an internationally respected figure in the scientific community".[2]
